I have an old-ish laptop I want to turn into a sort of home server. As this is for personal use at home, I'd like to use Arch. Probably an odd choice for a server but I like the Arch side of things.

One of the things I'd really like to run on it is a GitLab server. GitLab doesn't have an official means to install it on Arch, but there is a community package on the repo for it. From the page on the Arch wiki, it looks much more difficult to set up and configure (compared to an officially-supported distro). From the looks of it, it seems to be the from-source version of GitLab, which from reading through the docs, makes a lot of setup and maintenance much more difficult even after installation.

To anyone who runs GitLab on Arch: How much more difficult is GitLab on Arch compared to an Omnibus-based installation? How much more difficult is configuration and maintenance? What kinds of problems am I going to run into that I wouldn't on a GitLab-friendly distro? How much of the GitLab docs would be useless or inapplicable to me? Just how doable is this?
